In piezoelectric actuator between the nozzle design and installation of a hydraulic compensation, which the piezoelectric actuator below the pressure delivered to servo valve, this can not only make up for the processing system at the minimum tolerance, but also because of compensation Temperature changes in the length of the injector and the system itself Wear The resulting changes. Controller connected with the engine, combustion engine knock sensor monitoring process, the situation on the jet to adjust, so that each work cycle will advance the process of calculating good, the same amount of fuel injected into the cylinder, so the value of emissions Remain stable.

World production of diesel engine parts on a few large manufacturers are active in development and production of low-emission engines, with direct injection, common-rail fuel, and other emerging technologies, diesel cars will have a lot of the market.
